Improvement in fluting-machines



UNITED STATES THEODOBE M. TUCKER, OF NEWARK, NEW JERSEY.

IMPROVEMENT INV FLUTING-MACHINES.

Specication forming part of Letters Patent No. 117,487, dated July 25,1871*.

To all whom it may concern:

Beit known that I, TEEoDoRE M. TUCKER, of Newark, in the county of Essexand in the State of New Jersey, have invented certain new and usefulImprovements in Flirting-Machines; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon, in which- Figure l is a front view of the machine. Fig.2 is a vertical section through the line y y in Fig. l, showing the camand upper roller-frame in position for tluting. In dotted lines areshown the frame raised and the cam down. Fig. 3 is a horizontal sectionthrough the line m :v of the frame.

The nature of my invention consists in the use of a gravity-cam, whichis automatic in its operation, from its shape and gravity, and incombination with the frame of the upper roller and adjustinglever; alsoof a fluted standard, having two bearings on the end of the rollershaft,as hereinafter described. This invention is an improvement on myimproved iiutingma chine patented February 7, 1871.

In Fig. 1, A is the main bed-piece and frame. B is the movable frame orholder of the upper roller. C is the under roller, with its bearings inframe A. D is the top roller, with bearings in frame B. In the top barof the main frame A is a slot, to admit the combined rack and guide E,this guide being an integral part of the movable frame B. Theslide-guide E is a frame, with a rack on the inner sideof one of theuprights. Provision is made on the top bar of the main frame forbearings for a pinion, y, to be operated by the lever-handle w. By meansof the rack z and pinion y the upper roller D is lifted for theinsertion of the material to be uted between the rollers. The cam afalls by its own gravity when the frame is raised. To hold and guide thespiral springs of the required strength and tension without incumbranceto the frame, two projections, u and o, are cast upon the main frame,with holes from below through the bars to receive the spiral springs, asshown 'by the dotted lines, the teni sion of the springs s and t beinggraduated by the thumb-screws p and r, that are tapped through the solidtops of the projections u and fu. In Fig. 2, a is the gravity-cam,having a projection, b, as a weight, of suthcient power by its owngravity to turn the cam when relieved of pressure by the end of theframe B, when the machine is in operation. This cam has also on it aprojection or small cam, b', that serves as a catch to prevent it fromfalling down below the point shown in dotted lines in same view. It ismade somewhat eccentric on its upper periphery, and is grooved out tolighten the upper side, so as to turn readily by its own gravity. InFig. 3, c c and d d are the bearings of the frame A, giving two pointsof bearing on the ends of the shafts of the uted rollers, thus givingstrength and great .rigidity to the bearing, while the frame is madelight, thus having a leverage of two fulcrums in the 'bearings on theend of the shafts, which is of great importance when the pressure on therollers is at a distance from the bearing-points.

In the operation of my invention, when the work of iiuting is being donethe projection b of the cam a is in position, as seen in Fig. 2, therollers revolving without affecting the cam. In order to raise roller Dthe lever w is depressed, which revolves the cogs y operating rack z,and raising roller D to receive the goods to be liuted; and as soon asthe pressure from the springs s and t is taken off the cam a falls downby itsown gravity into the position seen in dotted lines in Fig. 2, thecam or small,

projection b catching against the frame B and stopping it. It is thusheld in this position until the goods are removed or inserted, as thecam will not turn by the pressure of the springs. To lower the roller Dit is only necessary to turn the crank, and the bite of theroller-bearing D catches the cam and turns it round to its position, asbefore, when the machine s ready again for iiuting. A

It will be seenthat this is a very important feature in my invention, asit acts :automatically, which is of vast importance when the rollers arefully heated, which is the case when it is at work. y.

Having thus described the nature of my in- In testimony that I claim theabove-described vention and its mode of operation, what I claim,invention for improvements in fiuting-ma-chines and desire to secure byLetters Patent, is- I have hereunto signed my nenne this 24th day of Thecam a constructed und operating as de- June, 1871. scribed, and incombination with the frame B Witnesses: THEODORE M. TUCKER. and lever woperating as described, and for the F. C. BOWEN, purposes set forth. Jo.C. CLAYTON.
